Concrete acoustic panel MH

The MH sound-absorbing panel consists of a double layer: a reinforced concrete structural layer and a sound-absorbing porous concrete layer.

The panels are supplied in the natural colour of the concrete, and may be coloured or decorated using patterns or shapes.

Panel Morphology

  • Material: CONCRETE
  • Is it absorbent for both sides?:
  • Assembly: SLIDING


  • Outer sides (exposed to noise): Porous concrete layer. Its ribbed geometry and porous material give the panel its absorption properties. It is made of porous concrete with ø 3 6mm gravel.
  • Inner side: Structural layer of HA-25 or HA-30 concrete up to 12 mm thick, reinforced with B500S steel mesh.


  • Good sound absorption capacity.
  • Due to its mass, concrete has excellent sound insulation capacity.
  • Structural durability.
  • Adaptation to the landscape and architectural constraints of each site due to its discreet appearance and the possibility of being painted in different colours.
  • Material with low environmental impact, recyclable and zero waste.

Acoustic features

  • According to Standard EN 1793-1, sound absorption index DLα (A2) is obtained.
  • According to Standard EN 1793-2, sound insulation index DLR (B3) is obtained.
